one of the good things about a choice when you had bill clinton pick al gore, when you had obama pick biden even when you had bush and cheney, they all, in their own way had their chemistry. but they also bring something to a ticket. or more important they do no harm. so they don't change the their at this. they don't change the essence of the message. so when cheney was picked, people might have said is he picking his daddy's friend or someone so old to help him. those are -- that could slap down a candidate but it doesn't change your whole thrust of your main selling point which was for romney, i could be a better steward of the economy than obama. so when -- you evaluate what happened yes so it was a great chemistry. >> bill: right. but politically -- again, it changed the focus of the campaign and then what did -- what did paul ryan bring? he didn't bring wisconsin. so you ended up with two candidates. had born in or lived in and paul ryan couldn't deliver either. >> here's the other thing. i think this is why these debriefs are constructive because it is hard to get this information at
